Abstract
There is provided an optical recording medium-manufacturing apparatus that is capable of accurately transferring a disk-shaped apparatus during a manufacturing process, and at the same time occupies a small installation area. A control section causes a cut-forming machine installed at a cut-forming location to form a cut in a resin layer of a disk-shaped substrate, then causes an indexing mechanism to rotate a transfer stage to thereby transfer the disk-shaped substrate formed with the cut to a central hole-forming location, and then causes a punching machine to punch a central hole.
